GT Range issues

[mkhuffman]

A bit harsh, but thanks for the reply none the less. It’s my first EV. I was just shocked that the range told us 100k less than the car actually gets. I know highway isn’t as good. But I didn’t expect to have such a drop in range driving in the summer with less than 2k in it. Hence why I asked if anyone heard about anything that’s been done (ie…anyone know if there is an update to address this). If 5000 threads are there, then you’d think it would be addressed by Ford. At a minimum, stop claiming 418 kms for a GT performance.
Don’t get me wrong, I LOVE this car. Just hoped someone might have an actual update.

Your GOM estimate does seem low. However, the GOM is just an estimate based on how you drive and the climate.

In the summer the GOM typically tells me I have around 240 miles of range. That is better than what you are getting but still less than the EPA range estimate. Why? A lot of my driving is on the highway.

Last winter my range dropped below your estimate and I was seeing a GOM of 180 miles. Why? Temperature and again, a driving history that includes a lot of highway.

We are now entering the cold months in North America. If you are in Canada, you are surely seeing below freezing temps at night. That will significantly reduce your range estimates. As it should.

Drive slower. Use less E-heat. And then you will go farther than the GOM predicts. Or drive fast and keep your cabin warm, and you might do worse than the GOM.

Really, I pretty much ignore the GOM in my car. Even though it is pretty accurate based on how I drive.

Buy some cali route 1 wheels and tires. 'That should pick up some more range for you. Or, pick up some forged magnesium 18 inch wheels from lightspeed racing for even more reduction in rolling resistance for max increase in efficiency. Drive like grandma, and maximize brake regen using the "L" button on the shifter. The L button only provides brake regen and doesn't apply the mechanical brake like one pedal driving. Also, the more aggressive driving modes also increase brake regen on pedal lift even if one pedal driving is turned off.

Rolling resistance comes from the tires, not the wheels. And those lightweight wheels will not improve your efficiency over the CA Rt1 wheels. At highway speeds the Lightspeed Racing wheels will significantly hurt your range, not improve it.

And not to continue to pile on (sorry) but I think you are incorrect about what "L" does. It works the same way as 1PD, and does not engage the brakes.

Maybe... just going by personal experience.

If you could tell me what the threshold is on one pedal driving where the car transitions from regen braking to mechanical braking (without guessing), that would be great.

The problem with cold weather is not Ford, not the Mach-E, it is the lithium ion battery. ALL lithium ion batteries perform more poorly when cold. That includes your cell phone...

When the car is stopped the brakes engage. Until then, it is all motor slowing when using 1PD. To engage the brakes you need to push on the brake pedal.

And my understanding is even in 2PD the majority of deceleration is regenerative braking unless stopping quickly.

I haven't read all of this but I can tell you your MME is just fine and the GOM (guess o' meter or in some cases stress o' meter) isn't the best way to judge range at all. There's many threads discussing. Enjoy your new MME GT and don't worry about what you see on the GOM. Look at mi/kWh and that's what you need to know.
